Answer:
= 1.7 cm
Explanation:
The magnification of the compound microscope is given by the product of the magnification of each lens
M = M₀
M = - L/f₀ 25/
Where f₀ and are the focal lengths of the lens and eyepiece, respectively, all values in centimeters
In this exercise they give us the magnification (M = 400X), the focal length of the lens (f₀ = 0.6 cm), the distance of the tube (L = 16 cm), let's look for the focal length of the eyepiece ()
= - L / f₀ 25 / M
Let's calculate
= - 16 / 0.6 25 / (-400)
= 1.67 cm
The minus sign in the magnification is because the image is inverted.
= 1.7 cm
Answer:
Both objects have the same magnitude of momentum.
Explanation:
If an object of mass is moving at a velocity of
, the momentum of that object would be
.
The (
) object is moving at a speed of
. The magnitude of the momentum of this object would be
.
Similarly, the momentum of the (
) object moving at a speed of
would be
.
Hence, the magnitude of momentum is the same for the two objects.
